I used command sudo ./snmpwalk -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1

and I have got info SNMPv2-SMI::enterprises.88888.1.7.1.0 = Hex-STRING: 00

Next, I tried to snmpset the OID .1.3.6.1.4.1.88888.1.7.1.0

sudo ./snmpset -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0 s "OPEN"
Error in packet.
Reason: noAccess
Failed object: SNMPv2-SMI::enterprises.88888.1.7.1.0

without -c public. I have got the same error

I am wondering it seems OID .1.3.6.1.4.1.88888.1.7.1.0 dows not exist?

Thank you.

Additional

I tried snmpget and seems OID .1.3.6.1.4.1.88888.1.7.1.0 exist

sudo ./snmpget -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0
SNMPv2-SMI::enterprises.88888.1.7.1.0 = Hex-STRING: 00

ASKER

Data types ids hex-string so I tried with option x

sudo ./snmpset -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0 x "OPEN"
.1.3.6.1.4.1.88888.1.7.1.0: Bad value notation (OPEN)

and

sudo ./snmpset -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0 x "0x2D"
Error in packet.
Reason: noAccess

My snmpd.conf contains

Restart snmpd and snmpset is timeout

Thanks

No I don't have rwuser netadmin and the snmpd.conf is empty file

ASKER

I just modified rwuser netadmin. Restart snmpd and result is timeout. How do I add com2sec?

Thank you.

I add

# sec.name source community
com2sec local localhost COMMUNITY

to snmpd.conf

Result=timeout

ASKER

Command

./snmpwalk -v 2c -c public localhost
Timeout: No Response from localhost

Location of file snmpd.conf

/usr/local/share/snmp/snmpd.conf

This file may not be a correct snmpd.conf I am finding other snmpd.conf

ASKER

I found snmpd.conf example file which contains com2sec. How can I bring this file to be a snmpd.conf of snmpd application?

I used snmpconf which create snmpd.conf at path

/usr/local/share/snmp

Error in packet.
Reason: notWritable (That object does not support modification)
Failed object: SNMPv2-SMI::enterprises.88888.1.7.1.0

I can confirm that files .c and .h config this OID read-write. Do you know how to check if OID can be modify?

Thank you.

ASKER

My mistake the OID is read-only. Let me modify MIB file .c and .h and try again.

Thank you.

Hello I found another error

tee@ubuntu:/opt/snmp/bin$ ./snmpget -v 3 -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0

Finally

./snmpset -v 2c -c public -u netadmin -l authPriv -a MD5 -A password -x DES -X password 127.0.0.1 .1.3.6.1.4.1.88888.1.7.1.0 s "OPEN"
SNMPv2-SMI::enterprises.88888.1.7.1.0 = STRING: "OPEN"

Seems it is working but when I tried snmpget

tee@ubuntu:/opt/snmp/bin$ ./snmpget -v 2c -c public -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0
SNMPv2-SMI::enterprises.88888.1.7.1.0 = STRING: "UNKNOWN_STATUS"
tee@ubuntu:/opt/snmp/bin$

Do you have idea why it is "UNKNOWN_STATUS"

Thank you.

In prior, the definition as hex string, open, is not valid. Your other attempts had 0x2D does setting that make a difference?

ASKER

Hello

It is difference <mib>.c file so the x "0x2D" is not exist anymore. The new one is s "OPEN"

tee@ubuntu:/opt/snmp/bin$ ./snmpget -v 2c -c public -u netadmin -l authPriv -a MD5 -A password -x DES -X password localhost .1.3.6.1.4.1.88888.1.7.1.0
SNMPv2-SMI::enterprises.88888.1.7.1.0 = STRING: "UNKNOWN_STATUS"
tee@ubuntu:/opt/snmp/bin$

I do not know which MIB you are using, in your prior response, the field type was indicated as HEX: String....
nor whether this SNMP OID when open is set, triggers an event at which point the status of the item is unknown.

ASKER

Hello Arnold,

Finally I is working once I config the snmpd.config with com2sec. Thank you. I will soon close this topic. Do you have additional info?

Info? I have, ir think I have broad knowledge, need to understand what additional info or concern, considerations you have in mind.
